Priming in a keg
So I am going to be priming my first keg soon and had a few questions. I know when I fill a bottle, I leave some head space for the CO2 to build up. When I fill my keg, and put the priming sugar in, how much head space do I need? I have 6 gallons of beer ready to go into a keg, but I only have a 5 gallon corney keg. Trying to figure out what to do with that other gallon.

Don't fill the keg so high that the beer is above the bottom of the gas-in tube. This can lead to back flow, and you'll get beer into your gas lines.

You'll also need to pressurize your keg (30PSI?) to ensure a complete seal, else your priming fermentation CO2 will just leak out of the keg, rather than carbonating the beer.

Take this with a grain of salt -- I tried to prime a keg and gave up. Now I just set them on gas at 12PSI and forget them for two weeks.

So fill below the gas in tube. Pressurize to 30 PSI. And it should be ready to sit and carb itself?

You don't need a lot of headspace in the keg. Put the rest in bomber bottles. 1/2 tsp of corn sugar in each. I fill the keg up then bottle the rest. Never looked.

You also do NOT use priming sugar with a keg. The co2 provides the carbonation.

Interesting, there's a lot of threads on here about priming your kegs with DME/Sugar as you would with bottles.

Wait wait, I am not supposed to put sugar in the keg to get the natural carbonation like a bottle? I have not heard of this. I have heard of the set and forget method of "force carbing", but I thought you could carb with sugar.

So this for goes transferring into a bottling bucket and just filling the bottles up off of your siphon with a wand on the end?

How did you figure this was a good amount of sugar into individual bottles... bomber as in 22 oz I assume?

You can carbonate a keg with DME/sugar, as you would bottles. Check the google search function on this site, there's a lot of people that carbonate their kegs with DME/sugar.

I see several threads about priming with sugar. Not sure what JayWeezie was talking about. Maybe he can explain further.
